Polysaccharides and related high molecular weight glycans are hugely diverse with wide application in Biotechnology and great opportunities for further exploitation. An Introduction to Polysaccharide Biotechnology – a second edition of the popular original text by Tombs and Harding – introduces students, researchers, clinicians and industrialists to the properties of some of the key materials involved, how these are applied, some of the economic factors concerning their production and how they are characterized for regulatory purposes.
Timely book gives account of the production and uses of polysaccharides. Focuses on the main developments. Also explains and illustrates how current work on polysaccharides may lead to major future developments in this field.
Polysaccharides provides information pertinent to the fundamental aspects of the chemistry of polysaccharides. This book discusses the methods used for the isolation, purification, and structural determination of the various types of polysaccharide. Organized into 14 chapters, this book begins with an overview of the almost universal occurrence of natural macromolecules in living organisms where they form a variety of functions. This text then examines the isolation of polysaccharides, which involves solubilization in aqueous solvents or in dipolar aprotic solvents. Other chapters consider the industrial applications of polysaccharides and of their derivatives. This book discusses as well the procedure for the isolation of wood polysaccharides, which involves the preparation of a holocellulose by the selective solubilization of the lignin. The final chapter deals with the classes of complex natural polymers in which the nature of the linkage of sugar units to other structural units have been established. This book is a valuable resource for biologists.
This authoritative reference work presents comprehensive information about one of the most important and most wide-spread classes of (bio)organic compounds: the polysaccharides. The comprehensive and thoroughly up-to-date handbook presents the sources, identification, analysis, biosynthesis, biotechnology and applications of important polysaccharides likes starches, cellulose, chitin, gum and microbial polysaccharides. Polysaccharides can exhibit complex structure and various functional activities. These bio macromolecules can therefore serve as raw materials for various different materials, e.g. rayon, cellulose acetate, celluloid and nitrocellulose; and they find multiple applications, for instance as surgical threads (chitin), as sources of energy, dietary fibers, as blood flow adjuvants, in cosmetics, emulsion stabilizers, film formers, binders, viscosity increasing agents or skin conditioning agenta, as food additives in gums, chewing gum bases and as vaccines. Polysaccharides form the basis for useful products, like xanthan gum, dextran, welan gum, gellan gum, diutan gum and pullulan. Some of the polysaccharide-derived products have interesting and useful properties and show biological activities, such as immunomodulatory, antibacterial, anti-mutagenic, radioprotective, anti-oxidative, anti-ulcer, antidepressant, anti-septicaemic or anti-inflammatory activities. All these applications and properties of polysaccharides are for the first time compiled in a thorough and comprehensive overview in the present work. This reference work is organized thematically in four parts: Part I. Polysaccharides: Occurrence, Structure, Distribution and Biotechnology. Part II. Methods. Part III. Bioactive Polysaccharides. Part IV. Polysaccharides as Food. This reference work is edited by experienced experts, all chapters are written by well recognized international specialists. It is useful to all those working in the field of botany, phytochemistry, pharmacy, drug delivery, molecular biology, metabolomics, forestry, environment, conservation, biotechnology and NGOs working for forest protection.
This book highlights recent developments in polysaccharides spurred by advances in biotechnology. Experts in the field describe the new biomass polysaccharides and their medicinal, food and industrial applications.
The bioactivity potential of marine polysaccharides has long been considered an underexploited aspect. These molecules found in seaweed, microalgae, bacteria, and animal fish (shellfish, mollusks, etc.) and the derived oligosaccharides need to be explored thoroughly with an interdisciplinary approach. They are an extraordinary source of chemical diversity, and the literature highlights many applicative fields, including the food industry, cosmetics, biomedicine, agriculture, environmental protection, wastewater management, etc. More recently, a new challenge has emerged: the exploitation of marine biomass as the source of sustainable energy to participate in the future replacement of fossil resources. Enzymatic Technologies for Marine Polysaccharides provides insight into the recent research developments of marine polysaccharides and their current and potential applications. The first section of the book explores the diversity of marine polysaccharides from various angles, including a description of the chemical complexity and current applications and new perspectives in food, pharmaceutical, cosmetics, and biomaterials offered by recent research. Efficient valorization of the marine polysaccharide biomass requires a rigorous analysis of the polysaccharides structure and their biological properties. The second section of the book concerns the development of extraction techniques and the improvement of the methods aimed at the characterization of their structure and function. Finally, the third and last section of the book articulates the enzymatic technologies from the discovery of novel enzymes to their production pipelines related to the fields of biorefinery, food, pharmaceutics, and other fine chemicals. Presents the latest research in marine oligosaccharides and polysaccharides Written by world-class researchers in marine enzyme technology Discusses the latest developments in extraction methods Presents a detailed overview of enzymatic routes for modification, production, and synthesis of marine oligosaccharides Contains extensive references at the end of each chapter to enhance further study
The Polysaccharides, Volume 2 is a seven-chapter text that presents the status of polysaccharide chemistry and related aspects of biochemistry. The opening chapter is concerned with the major classifications of polysaccharides, such as homoglycans and diheteroglycans. The succeeding five chapters discuss the occurrence, usage, structural studies, conformation, and derivatives of specific carbohydrate group, including cellulose, plant, algal, bacterial, and fungal polysaccharides. The last chapter deals with the industrial application and economic aspects of polysaccharides. This book will prove useful to chemists and biochemists working on polysaccharides and other complex carbohydrates.
Functional Polysaccharides for Biomedical Applications examines the fundamentals and properties of these natural materials and their potential biomedical applications. With an emphasis on therapeutic and sensing applications, the book also reviews how polysaccharides can be modified for tissue engineering applications. Sections discuss the basics of polysaccharides, give an overview of the potential applications, look at novel materials and technologies for use in tissue regeneration and therapeutics, and detail current biomedical applications. With a strong focus on materials, engineering and applications, this book is a valuable resource for those with an interest in harnessing the biomedical potential of natural polymers. - Describes strategies for developing polysaccharides-based biomedical devices - Illustrates concepts and encompasses scope for clinical development - Provides advanced and comprehensive information on biomedical constructs
